Olli's place is lovely! The place is really really big, very near everything in bangkok, and the rooftop pool is to die for. Very convenient given theres a 711 right in front of the condo, and right behind is actually a place where workpeople can eat.
Olli is also very helpful with our concerns. Just message him in airbnb and he replies in 30mins (most of the time even less!). His place is full of tips and maps so that you can explore bangkok even without taking tours.
Definitely a recommended place to stay when exploring Bangkok.
